A system detecting actuation of a pre-determined function, the actuation executed by touch contact with a pre-determined path associated with the function on a touch-sensitive surface of an object, including: at least two separate sources for transmitting bulk acoustic waves in the touch-sensitive surface, configured to generate acoustic interference between the transmitted waves; at least one bulk acoustic wave receiver after propagation and interference thereof in the touch-sensitive surface, configured to supply a reception signal based on the acoustic waves received; a mechanism storing plural reference spectral signatures associated with the pre-determined path, each of the spectral signatures associated with a localization of a touch on the pre-determined path; and a mechanism detecting actuation of the pre-determined function by comparing at least one spectral signature of the reception signal to a spectral envelope, or reference spectral envelope, of the plural reference spectral signatures associated with the pre-determined path.

A system for detecting and localizing at least one touch on a touch-sensitive surface of an object includes: at least two separate sources transmitting bulk acoustic waves in the touch-sensitive surface, configured to generate acoustic interference between the transmitted waves; at least one bulk acoustic wave receiver after propagation and interference thereof in the touch-sensitive surface, configured to supply a reception signal based on the acoustic waves received; a mechanism localizing at least one touch on the touch-sensitive surface of the object by comparing certain spectral characteristics of the reception signal to a set of reference spectral characteristics; a mechanism measuring a temperature of the touch-sensitive surface, and a mechanism adapting the spectral characteristics of the reception signal or the reference spectral characteristics by a frequency shift of at least some of the spectral characteristics as a function of the temperature measured.

An intelligent interface device for grasping an object includes a manipulating robot comprising a hinged arm provided with a clamp at its free end and equipped with at least one camera, a computer with a display screen and an input unit, means for controlling the clamp, means for displaying the video image of the object taken by a camera on the display screen, means for graphically identifying a selection area surrounding the object in this image using the input unit.
